Plus-X Dual IP-8 Adapter

Upgrade your ARC-16 without Rewiring

Upgrading legacy ARC-16 systems is faster and more affordable than ever. The Plus-X Dual IP-8 Adapter connects to up to two ARC-16 IP-8s using the same DB37 cables as the ARC-16. Not a single channel needs to be rewired to upgrade to the ARC Plus Touch, saving hours of work.

Cost Effective Upgrade

The Plus-X Dual IP-8 Adapter includes all the I/O needed for up to 16 channels, eliminating the need for additional input and output units.

With its 256 channel capacity and Ethernet I/O architecture, a single ARC Plus can replace multiple ARC-16 systems. Simply install a Plus-X Dual IP-8 Adapter at each site.
